the relatively large number of genera confined to the two 
regions or extending only to neighbouriug islands. Six genera’ 
are confined entirely to the Philippines and Celebes, and of 
these, Spiraeopsis, Wallaceodendron and Strophioblachia are mono- 
typic, Acrosorus has two species in the Philippines and one in 
Celebes, Reinwardtiodendron one species in each, and Anompanar 
two in Celebes and one in the Philippines. In addition to the 
above, the monotypic genus Koordersiodendron is known only 
from the Philippines, Celebes and New Guinea, Cudilia, a mono- 
typic genus, from the Philippines, Celebes and Amboina, Pothov- 
dium, a monotypic genus, the Philippines, Celebes and the Moluc- 
cas, Z'ristira, with about five species, three in the Philippines, 
one in Celebes and one in the Moluccas, while Zepzniopsis, also 
a monotypic genus is at present known only from the Philip- 
pines and Ternate. 
The list given above by no means represents all the evidence 
of close floristic relationship between Celebes and the Philip- 
pines, for a considerable number of species are known that 
are found in the two regions, that are also found in some 
other islands near Celebes. The Philippines and Celebes with 
Borneo present: Hymenolepis platyrhynchos Kze., Loxogramme tridi- — 
folia Copel., Ficus Forstenii Mig. (also in Timor), Drimys piperita 
Hook, f. (also in New Caledonia), and J/allotus Korthalsti Muell. 
Arg.; with the Moluccas: Podocarpus Rumphii Bl. (also in New 
Guinea), Pothoidium Lobbii Schott, a monotypic genus, Maca- 
ranga hispida Muell. Arg., Tristira, as mentioned above, and 
Nycticalos cuspidatum Miq.; with Amboina: Spathiphyllum commu- 
tatum Schott, Garuga abilo Mery. (also in Samoa), Cudilia Blanco 
BL, a monotypic genus; with New Guinea: Dennstaedlia ery- 
throrachis Diels, Medinilla Te eysmanni Miq., and Koordersiodendron 
pinnatum Merr., the latter a monotypic genus; with Timor: 
Vournefortia sarmentosa Lam.; with Samoa: Oleandra Whitmeei 
Bak.; with Batjan: Péeris opaca J. Sm.; with the Solomon Islands: 
Vectaria menyanthidis Copel.; with Polynesia: HHumata botrychiot- 
des Kze.
